Levels and dynamic changes of serum fibroblast growth factor 23 in hypophosphatemic rickets/osteomalacia

引用

Chinese Medical Journal 2010年第9期123卷 1158-1162页

作者： XIA Wei-bo JIANG Yan LI Mei XING Xiao-ping WANG Ou HU Ying-ying ZHANG Hua-bing LIU Huai-cheng meng xun-wu ZHOU Xue-ying Department of Endocrinology Key Laboratory of EndocrinologyMinistry of HealthPeking Union Medical College HospitalChinese Academy of Medical SciencesBeijing 100730China

Background Hypophosphatemic rickets/osteomalacia is a group of diseases characterised by defective mineralization of bone due to hypophosphatemia and low 1,25-dihydroxy vitamin D. To explore the role of fibroblast growth factor 23 （FGF-23） in the regulation of phosphate homeostasis, we measured the circulating concentrations of this growth factor in healthy individuals and in patients with hypophosphatemic rickets/osteomalacia. Methods Nineteen patients with hypophosphatemic rickets/osteomalacia were included in hypophosphatemic group （HP, 12 female and 7 male, mean age was 30 years）, and 19 healthy age-matched individuals served as the control group. Full length FGF-23 fragments were measured by two-site enzyme-linked immunosorbent *** Mean FGF-23 concentrations were significantly higher in the HP group （（87.4±43.6） pg/ml） compared with the control group （（19.2±6.16） pg/ml; P 〈0.001）. In 1 patient with tumour-induced osteomalacia, serum FGF-23 concentrations were 84.1 pg/ml; these concentrations were normalized 2 hours after a hemangiopericytoma resection （7.8 pg/ml）. Subsequently, serum 1,25（OH）2 vitamin D3 concentrations significantly increased from 21.3 pg/ml to 89.3 pg/ml, and serum phosphorus levels were normalized. Conclusions Serum FGF-23 concentrations were markedly elevated in patients with hypophosphatemic rickets. FGF-23 plays an important role in the pathogenesis of hypophosphatemic rickets/osteomalacia.

Machine learning for prediction of retained austenite fraction and optimization of processing in quenched and partitioned steels

引用

Journal of Iron and Steel Research International 2024年第8期31卷 2002-2013页

The metastable retained austenite(RA)plays a significant role in the excellent mechanical performance of quenching and partitioning(Q&P)steels,while the volume fraction of RA(V_(RA))is challengeable to directly predict due to the complicated relationships between the chemical composition and process(like quenching temperature(Qr)).A Gaussian process regression model in machine learning was developed to predict V_(RA),and the model accuracy was further improved by introducing a metallurgical parameter of martensite fraction(fo)to accurately predict V_(RA) in Q&P *** developed machine learning model combined with Bayesian global optimization can serve as another selection strategy for the quenching temperature,and this strategy is very effcient as it found the"optimum"Qr with the maximum V_(RA) using only seven consecutive *** benchmark experiment also reveals that the developed machine learning model predicts V_(RA) more accurately than the popular constrained carbon equilibrium thermodynamic model,even better than a thermo-kinetic quenching-partitioning-tempering-local equilibrium model.
